Miranda Lambert is now officially a Parrothead. The country music superstar was in attendance for Jimmy Buffett's July 6 concert at St. Louis' Hollywood Casino Amphitheatre, but Lambert didn't just enjoy the show as part of the crowd. She joined him onstage.
A few fans were able to capture the duet on video, though one Buffett fan wasn't completely sure what was going on when Lambert crashed the show.
"Who is this [Miranda Lambert] person who crashed my [Jimmy Buffett] concert? Maybe she has a future in the biz," a fan captioned a video of the duet.
Despite being a bit of a mystery to some in the crowd, Lambert clearly had the time of her life at the show.
"All smiles! Last night we got to hang with [Jimmy Buffett] in St. Louis! And I got to join him onstage for "Margaritaville." It was my first time to see him. I'm a [parrot head] for life now!" Lampert captioned a photo of herself backstage with Buffett that she posted on Instagram.
